Function
function
Catalyzes the transfer of endogenously produced octanoic acid from octanoyl-acyl-carrier-protein onto the lipoyl domains of lipoate-dependent enzymes. Lipoyl-ACP can also act as a substrate although octanoyl-ACP is likely to be the physiological substrate.
Catalytic activity
- octanoyl-[ACP] + L-lysyl-[protein] = N6-octanoyl-L-lysyl-[protein] + holo-[ACP] + H+
Pathway
Protein modification; protein lipoylation via endogenous pathway; protein N6-(lipoyl)lysine from octanoyl-[acyl-carrier-protein]: step 1/2.
